The main problem is the presence of the category name before the headers and data. This creates a condition to consider while looping over the lines because when we read a category name we need to consider 4 rows while when reading the transaction data we have to loop over 3 rows. However there is … Read more
You could start by taking a look at Handle By Mark Russinovich. Just run it as administrator and it will return all files used by all processes. You could use the following syntax to put the results into a text file: handle.exe > log.txt Afterwards, you may use PowerShell to extract the information about the … Read more
It means, that the code it returning an object, which is System.Byte[] array. ArrayList[i].ToString(); // System.Byte[] ..no matter how many times you do it. It will always return to be the same. Use this instead using System.Text; // <– add this // inside the code for(i = 0 ; i <= ArrayList.Count ; i++ ) … Read more
If input is contained in a std::string you can find the length as stated by Ravi. If it’s a C string you find the length with int len = strlen(INPUT); In C/C++ upper case is normally used for constants so it’s better to name the string input, not INPUT. 0 solved How to find the … Read more
The Microsoft Developer Network has a great comparison: Although StringBuilder and String both represent sequences of characters, they are implemented differently. String is an immutable type. That is, each operation that appears to modify a String object actually creates a new string. For example, the call to the String.Concat method in the following C# example … Read more
C does not have any functionality to conveniently get a web site like the standard Java libraries. You can use libcurl which is a fairly convenient way of doing it or writing everything in sockets yourself in which case I’d say familiarise yourself with C network programming first: Beej’s Guide to Network Programming solved get … Read more
You can use reflection to access a field by its name : FieldInfo ageField = typeof(Person).GetField(“age”); int age = (int) field.GetValue(person); solved C# Accessing field syntax
Are you using str[n]cpy? You can’t! Base64 encoded data can contain null characters, which C string processing functions interpret as end-of-string. Use memcpy instead of str[n]cpy, memcmp instead of strcmp, etc. These functions require you to know your data size, but I believe that you do know it. Also if you’re not very confident about … Read more
I would do this like this: std::ifstream infile(“myfile.txt”); char ch; while(infile.get(ch)) { … process ch … } This avoids the problems that appear on the last character, or having to read a character before the first iteration of the loop. solved How to read the entire content of a file character by character?
A function to caesar an alphabetic char should be like (decomposed in elementary steps): int caesar_lower(int c,int key) { int v = c-‘a’; // translate ‘a’–‘z’ to 0–25 v = v+key; // translate 0–25 to key–key+25 v = v%26; // translate key–key+25 to key–25,0–key-1 v = v+’a’; // translate back 0–25 to ‘a’–‘z’ return v; … Read more
I think it should be something like this : for(;a<b–;){ for(d += a++ ; a != c ; ) { d += a++; } c+= a&b } The above logic works ! I ran both programs as below and they output the same result : Program1:[derived from your program 1] #include<stdio.h> int main(){ int a=10,b=10,c=10,d=10; … Read more
auto compare = [](int x, int y) { return x < y ? “x is less than y” : “x is greater than y”; }; 5 solved How can I return string instead of bool in lambda?
Nobody found the answer. But it is easier to downvote than solving code issues ! So, here is the answer, i hope it will help other guys who encounter the same problem. 1 / Assuming you build a query which creates a table with custom columns named “Name, State, Nb, Avg, Min, Max : string … Read more
Here’s some code which shows what’s going on (in excruciating detail): #include <stdio.h> int main(void) { int a = 11; int b = 20; int x = -1; int y = -1; int *ip1 = &a; int *ip2 = &x; int **ipp = &ip2; printf(“Addresses:\n”); printf(” &a = %p\n”, (void *)&a); printf(” &b = %p\n”, … Read more
Assuming the statement you’re testing is actually ‘How is the weather’ then your if statement is working as expected. Your checks are seeing if the statement contains ‘weather’ and ‘what’ OR contains the word ‘how’ (note the lower case). As your phrase doesn’t contain the word ‘what’ the first check (for the words ‘weather’ AND … Read more
